It is preferred that, the reinforcement support base is cylinder or turbination.
It is preferred that, the bottom cutting edge thickness of the drift is less than 5mm.
It is preferred that, guide pillar, guide pin bushing are provided between the upper die and lower die.
The beneficial effects of the invention are as follows：A kind of hub squeezes punching forging mold, and it includes upper die and lower die, it is described on
Mould includes upper bolster, punch holder, drift, and the lower mould includes punch-pin, stripper, and the punch-pin is provided with for being used to accommodate wheel
The die cavity of the cylindrical end of hub unit, the bottom of the die cavity is provided with the material returned hole of downward insertion, a diameter of D of the die cavity,
Cylindrical end a diameter of d, the D=d+3mm of the pre- forging of punching are squeezed, the top of the die cavity is provided with the cylindrical end root with pre- forging
The corresponding transition arc in portion, the bottom up of the die cavity convexes to form small boss, is set between the small boss and material returned hole
Have cut-out cutting edge, scientific structure of the present invention is first extruded pre- forging by drift, metal simultaneously downwards, to circumferencial direction
Flowing, then in the presence of drift, cut-out cutting edge, the metal cutting flowed downward completes to squeeze simultaneously by one set of die
Pressure, punching, reduce mould usage amount, improve production efficiency.

Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not the reality the present invention
Apply scope limited to this.
As shown in Figure 1, Figure 4, Figure 5, the hub of the present embodiment squeezes punching forging mold, and it includes upper die and lower die, institute
Stating mould includes upper bolster 1, punch holder 2, drift 3, and punch holder 2 is fixed on upper bolster 1, and the upper end of drift 3 is threadably secured
In in punch holder 2, the lower mould includes punch-pin 4, stripper 5（Lower mould can also include die shoe, in the present embodiment, punch-pin 4 with
Die shoe is integrated）, the punch-pin 4 is provided with the die cavity 41 for the cylindrical end for accommodating hub, the die cavity 41
Bottom be provided with the material returned hole 42 of downward insertion, a diameter of D of the die cavity 41 squeezes the cylindrical end diameter of the pre- forging of punching
For d, D=d+3mm, the top of the die cavity 41 is provided with transition arc 43 corresponding with the cylindrical end root of pre- forging, the mould
The bottom up of chamber 41 convexes to form small boss 44, and cut-out cutting edge 45 is provided between the small boss 44 and material returned hole 42.Fig. 2
For the pre- forging by forging, die cavity 41 is put it into, is positioned by 43 pairs of pre- forging of excessive circular, then under drift 3
Row is stretched into from the bowl-shape deep bid of pre- forging, extrudes the cylindrical end of pre- forging, and portion of material can downwards be extruded in vertical direction, part
Material flows in the horizontal direction in the presence of extruding force, causes the diameter of pre- forging to increase to D by d, the length of cylindrical end is omited
Micro- increase.Because the cavity between cylindrical end and die cavity 41 contains the metal of most of flowing, cylindrical end is substantially reduced long
The increase of degree（Need in follow-up finishing）.Drift 3 is continued traveling downwardly, and in the presence of drift 3, cut-out cutting edge 45, will be flowed downward
Metal cutting formation through hole, unnecessary material fallen from material returned hole 42, and the present embodiment is completed to extrude, rushed simultaneously by one set of die
Hole, reduces mould usage amount, improves production efficiency.
The design of the cut-out cutting edge 45 of the present embodiment can separate in order to the metal flowed downward with the metal of side, so that
Form through hole.
Further, the top of drift 3 is connected by screw thread with the punch holder 2, and the middle part of the drift 3 is provided with
Outwardly reinforcement support base 31, the upper top surface of the support base 31 contradicts the punch holder 2.Because drift 3 is longer, strengthen
Support base 31 can increase the lifting surface area of drift 3, reduce the impact that drift 3 is subject to, prevent the too early flexural deformation of drift 3.
Further, it is cylinder or turbination to strengthen support base 31, and Fig. 4 show turbination.
Further, the bottom cutting edge thickness of drift 3 is less than 5mm, the height of the working portion of drift 3 is reduced, so that greatly
Contact area of the forging when being separated with drift 3 is reduced greatly, the abjection resistance that drift 3 is deviate from from forging is effectively reduced.
Further, guide pillar 6, guide pin bushing 7 are provided between upper die and lower die.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than to present invention guarantor
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention
Matter and scope.
